CAN-SEALING DEVICE.

Application filed April 17, 1922.

To all whom it may concern:

Be it known that I, CLARENCE VERWAY, a citizen of the United States, residing at Illuskegon, in the county of Muskegon and State of Michigan, have invented a new and useful CainSealing Device, oil which the tollowing is a specification.

This invention is a device for use in apilying metal tops to glass preserving cans,

s. or similar containers.

After the metal cap of the standard preserving can or ar has once been applied to the container and subsequently removed, it is often ditiicult to again obtain a perfect sealing joint with the same cap, principally because the sealing flange of the cap is slightly distorted in the remova. One of the objects of the invention is to overcome this dii'tlculty by providing a simple and inexpensive device by means of which any inequalities or imperfections in the sealing edge of the cap may be smoothed out, and a perfectly tight sealing engagement assured. A further object is to provide simple means for holding the cap against movement during the application of the sealing pressure to the flange thereof. A further object is to provide a device in which the cap holding and the flange pressing elements are combined in a single unitary structure, whereby an implement is provided which may be quickly and conveniently engaged with the cap, and utilized to apply the latter to a can or jar, and which will enable the operator to firmly hold the cap during the application of the sealing pressure.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawing:-

Figure 1 is a side elevation illustrating a cap sealing device constructed in accordance with the invention. Figure 2 is atop plan view thereof. Figure 3 is a transverse sectional view on the line 33 of Figure 2.

Referring to the drawing. 10 designates a standard can or jar cap of the well-known Mason type, which is shown as gripped by the curved portion 1]., of a cap-holding wrench, which is provided with diverging operating arms 12. Said wrench may be made of any desired material, but it is preferred to construct it of a single integral piece of resilient metal, as shown.

A carrier plate 13, preferably circular in form, is supported by the wrench, being Serial No. 553,783.

provided with. an ear 1 1-, which engages an offset 1P ot the gripper portion 11, or" said wrench. Said plate is also provided with :1 depending flange 15, disposed in a posltion diametrically opposite to the car 14. The arms 12 of the capholding wrench project through openings 16 in the flange 15, said openings being elongated to provide necessary clearance for lateral movement of said arms in applying clamping pressure to the cap 10 and limiting the separation of said arms.

Pivotally connected to the center of the plate 13. by means of a rivet or the like 17, is a sealing arm 18, which is provided with a depending cap-engaging presser member 19. The sealing arm and presser member may be constructed in any suitable or preferred manner. In the drawing the same is shown as constructed or a strip of. metal, bent back upon itself at 20, and provided with an integral oftset portion forming the presser member 19. i

In practice, the circular or gripping portion of the wrench is normaly large enough to receive the cap 10. When it is desired to apply a cap to a can or jar, it is inserted into the gripping portion 11 of the wrench, and firmly held therein by moving the arms 12 toward each other. This may be conveniently effected by the operator holding the arms 12 in one hand and inserting the cap with the other, the cap and the sealing device being supported by the wrench. The cap is then screwed home on the can or jar, the wrench providing ample leverage for this purpose. After the cap has been positioned, the operator grasps the arm 18, and swings it in a. circular path, simultaneously pressing downwardly thereon, to cause the sealing member 19 to exert a swedging presure upon the sealing flange of the cap. During this operation the wrench is held by one hand and the arm 18 manipulated by the other hand. The effeet of the said operation is to straighten out any distortions or irregularities in the sealing flange, and at the same time to force the latter into intimate engagement with the rubber gasket usually employed in con nection with preserving jars or cans, to insure an air-tight joint between the jar and the cap flange.

The advantages of the invention will be readily apparent. By means thereof, can caps which have been previously used, and

which heretofore had to be discarded because of imperfections incident to their previous use, may be utilized, and perfect sealing obtained by smoothing out the irregularities in the sealing flange, in an exceedingly simple manner. The several parts of the device being combined in a single unitary structure, are arranged for convenient manipulation by the housewife, and may be be effectually operated without the exerciseof any high degree of skill.

Having thus explained the nature of the invention, and described an operative manner ofconstructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the forms of its use, what is claimed 1. A can sealing device of the character described comprising a carrier plate, a cantop-gripping member having a portion se cured to the edge of said plate and a sealing arm pivotally engaging said plate and movable in a circular path, said arm having a downwardly bent portion forming a presser member.

2. A can sealing device comprising a carrier plate, a can-top-gripping member having a portion secured to the peripheral edge of said plate, and a sealing armengaging said plate, said arm having a portion bent back upon itself and provided with a deflected extremity forming a presser member; i

3, A can sealing device of the character described comprising a wrench member formed with a resilient curved portion and diverging arms, a carrier. plate secured to the curved portion of the wrench and having a depending curved flange through which the arms extend, and a can toppresser arm having one end pivotally connected to the center of said plate.

A. A can sealing device of the character described comprising a wrench formed with a resilient curved cover-engaging portion and diverging arms, said curved portion having an offset portion, a carrier plate supported by said curved portion and having an ear engaging the offset portion of the wrench, and can-cover-sealing means movably connectedwith said carrier plate.

5. A can sealing device of the character described comprising a wrench formed with a resilient curved cover-engaging portion and diverging arms, a carrier plate having an ear engaging said curved portion, and can-cover-sealing means movably connected with said carrier.

6. A can sealing device of the character described comprising a Wrench formed with a resilient curved cover-engaging portion and diverging arms, a circular carrier plate secured to said resilient portion and having a flange provided with openings through which said arms pass, and a can-coversealing member movably connected to said plate.

7. A can sealing device of thecharact'er described comprising a wrench formed with a resilient curved cover-engaging portion and diverging arms, a circular carrier plate having an ear secured to said curved portion of the wrench and having a flange provided with openings through which said arms pass, and a sealing arm pivoted at one end to said plate and provided with a depending presser member.

In testimony whereof I have hereunto set my hand.
